Hello,I was just wondering what are the general differences in the sonics of cd players that use upsampling as opposed to regular oversampling are?Also, how do the sonics of the older cd players that did not use either oversampling or upsampling compare to the newer ones that do?Which do you prefer and why?Thanks for your answers.

Now you can ask about CD players that Upsample against those that do not.

The data is the data. What is there is all there is. Upsampling does not uncover any new data. It basically stretches the data to a longer word length by estimation, by using all kinds of fancy math equations.

For me, I only care how the player sounds. How it gets there, whether it Upsamples or not I do not consider much. I do not think one way is always superior than the other.
